> You've done a search of the forum archives for Python, right?
Yes, unfortunately there doesn't seem to be anything about this. I've got a couple of other ideas to try:
* Early binding of Python.
* Passing a variant from Python to other non-Amibroker COM object.
* Passing a variant to one of the variable parameter methods in Amibroker.
Thanks,
Peter.
